POWDER-PUNCH AND FUSE-HOLDER.

Specification of Letters Patent.

Patented Jan. 1, 1918.

Application filed J u1y 16, 1917. Serial No. 180,827.

. To all whom it may concern Be it known that I, DANIEL J. WA'rrs, asubject of Great Britain, residing at Iron River, in the county of Ironand State of Michigan, have invented certain new and useful Improvementsin" Powder-Punches and Fuse-Holders, of which the following is aspecification.

M invention relates to improvements in com ined powder punch andblasting-fuse holders.

The object of my invention is to provide a powder punch which incombination with a U tube will form a holder for fuses used in blasting.The U tube will also cover the punch and protect it.

My device is of especial use, when in blasting it becomes necessary tohold a number of fuses together in one place. It also holds these fusesin such a positive manner that they can not shake loose.

The manner of fastening is simple, ouick and effective. The clampinggrip of the tubing is increased as the short end of the powder punch ispressed into the opening of the tu c. It will be noted that the punchconsists of two arms, one long and one short which are connected by acurved portion forming a handle. The arms are in the same plane but notparallel, the arms diverging as they leave the handle. This spreading ofthe arms forms a spring, shown later, exerts a leverage when inserted inthe tubing. Thetubing is cut and split so that when bent upon itself toform a U the bends will be square. The advantage in this form of U is,it avoids soldering.

When it is desired to clamp one or more fuses, they are placed betweenthe two U arms of the tubing and these U arms are ressed together untilapproximately paralel. The arms of the powder punch are now insertedinto the hollow U arm, but to do this the handle of the powder punchmust be held in such a manner that the arms may be ressed into aparallel position in order that they shall enter the parallel arms ofthe U tube.

Referring to the drawings, Figure (1) denotes the powder punch. Fig. (2)shows the tube bent in U-shape. Fig. (3) is a view of the tube showingslashes or cuts therein. Fig. (4)-J hows the powder punch and the whichas will be to form a loop and terminating in the twoarms a a the arm ais much longer than its companion arm, its end being pointed as shown inthe drawings and serves as a powder punch. The arm a is short and servesas a support or spring to hold the arms of the U tube B in parallelrelation. The tube B is preferably made of metal and is bent upon itselfso as to form a U with parallel arms.

In Fig. (4) of the drawing I have shown in dotted lines the fuses C,held in place between the arms b b of the tube B.

It is evident that the fuses placed between the arms of the U tube B areheld resiliently between them and that when the arms of the powder punchare inserted into the bores of the tube arms and released therein, thatthe resiliency of the metal bar will cause it to bindingly grip theinterior of the tube, thereby sustaining said tube arms in parallelrelation and positively clampin the fuses between the arms of the tube.It 1s clear that when the powder punch and tube are pulled apart thatthe fuses will drop from between the arms of the U tube.

Having thus shown my invention, what I claim and desire to secure byLetters Patent is:

1. A fuse holder and powder punch consisting of a round bar bent over onitself forming diverging resilient arms of unequal length, and a, U-haped tube the arms of which are adapted to receive said arms; wherebythe arms of said bar and tube may be detachably connected.

2. A fuse holder and powder punch consisting of a bar bent over onitself forming non-parallel arms and a U-shaped tube the arms of whichare adapted to receive the exterior of said arms whereby the arms ofsaid bar and tube may be detachably connected.

In testimony whereof I aiiix my signature in the presence of twowitnesses.

DANIEL JAMES \VATTS.
